Yea its a gun mod but I tried that Universal addon and I tried to save and it did but it only works if I turn on that code. And I don't like that code at all cause its straight up saying your a hacker and the rapid and lock on distance makes it too much of a code. I just want tthe attachment part of it. I just need a code that I can turn on the can let me change the muzzle part of the gun and let me attch it with a muzzle brake. My loadout is an F2K with laser sight, low scope, grip and a deagle with laser2.
